/***
*limits.h - implementation dependent values
*
* Copyright (c) 1985-1993, Microsoft Corporation. All rights reserved.
*
*Purpose:
* Contains defines for a number of implementation dependent values
* which are commonly used in C programs.
* [ANSI]
*
*Revision History:
* 06-03-87 JMB Added support for unsigned char max values
* 08-19-88 GJF Revised to also support the 386
* 04-28-89 SKS Put parentheses around negative constants
* 08-17-89 GJF Cleanup, now specific to 386
* 10-30-89 GJF Fixed copyright
* 11-15-89 KRS Add MB_LEN_MAX, fix CHAR_MIN/MAX, order like ANSI spec.
* 03-01-90 GJF Added #ifndef _INC_LIMITS stuff
* 02-21-91 KRS Change MB_LEN_MAX to 2 for C 7.00.
* 03-30-92 DJM POSIX support.
* 08-22-92 SRW Fix value of _POSIX_ARG_MAX
* 12-14-92 SRW Fix value of _POSIX_ARG_MAX again
* 12-14-92 SRW Back merge MattBr's changes from 10/29/92
* 01-15-93 CFW Added __c_lconvinit dummy variable.
* 01-28-93 SRW MAke PATH_MAX for Posix right for Posix
* 02-01-93 CFW Removed __c_lconvinit vars to locale.h.
* 03-10-93 MJB More fixes for Posix.
* 04-20-93 GJF Changed SCHAR_MIN, SHRT_MIN, INT_MIN, LONG_MIN
*
